I started smoking at 12 years old. I smoked for 21 years everyday 7 to 10 cigs. With the usage of E-cigs I was able to quit smoking in just two weeks. While I never tried anything else but cold turkey, I can tell you this was more effective than any other attempt that I had made. I think the best part of vaping is that as one progresses one eventually reduces their nicotine level, sometimes to zero. Vaping is a good way to quit, and an excellent hobby as well.
